Verify the incidence and rate of joint and muscle injuries with the practice of CrossFit® and the potential risk factors for injuries in men and women.
A total of 184 CrossFit® participants (97 men and 87 women). A questionnaire was conducted based on characterization, training routine, injuries, and additional information. The incidence refers to the number of new cases of injury in the sample during the CrossFit® training. The injury rate was calculated by estimating the number of weekly training hours and converted into the number of injuries per 1000 training hours.
Among the participants, 38.6% reported some type of injury, being joint injuries (83.1%) and/or muscle injuries (45.1%). The injury rate was 3.4/1000 h, with men having a higher rate. The location of the joint injuries was shoulders, wrists, and elbows, in addition to the lumbar spine in women. As for muscle injuries, the deltoid, upper back muscles, and quadriceps femoris were the most reported in men and deltoid, trapezius, upper back muscles, and gastrocnemius in women.
A better understanding of the anatomical distribution of the injuries may help coaches prescribe the most adequate workout that may reduce the likelihood of injuries occurring in CrossFit® training participants. It was demonstrated that gender, experience, weekly frequency, and previous injuries are important factors, and professionals must be concerned with the assessment of the participants and with an individualized progression in order to avoid risks.
验证 CrossFit® 训练中男性和女性关节和肌肉损伤的发生率和损伤率，以及潜在的损伤风险因素。
共有 184 名 CrossFit® 参与者（97 名男性和 87 名女性）。根据特征、训练常规、损伤和其他信息进行问卷调查。发病率是指 CrossFit® 训练期间样本中新发生的损伤例数。损伤率通过估计每周训练小时数来计算，并转换为每 1000 小时训练的损伤数。
参与者中有 38.6%报告了某种类型的损伤，包括关节损伤（83.1%）和/或肌肉损伤（45.1%）。损伤率为 3.4/1000 小时，男性的损伤率更高。关节损伤的部位为肩部、手腕和肘部，女性还包括腰椎。至于肌肉损伤，男性报告最多的是三角肌、上背部肌肉和股四头肌，女性报告最多的是三角肌、斜方肌、上背部肌肉和腓肠肌。
更好地了解损伤的解剖分布可能有助于教练开出最合适的锻炼方案，从而降低 CrossFit® 训练参与者受伤的可能性。性别、经验、每周频率和先前受伤是重要因素，专业人员必须关注参与者的评估和个性化进展，以避免风险。
